Go Direct® pH Sensor, order code GDX-PH, $89
Specifications and User Guide
- Primary Test: It should read approximately 4 in its storage solution.
- Secondary Test: Take readings in fresh buffers, NOT distilled water! The pH reading should be within 0.2 pH units of the pH buffer. For example, if using a pH 4.0 buffer, your reading should be between 3.8 and 4.2.
If no buffers are available, try it in vinegar (~ pH 2.5-3.5) and ammonia (~ pH 10.5-11.5). If readings do not change when the sensor is placed in different solutions, the sensor is possibly defective or damaged.
